Description

[Technical field]

[0001] The present disclosure relates to a technique for issuing an alarm when an abnormal impact occurs to a vehicle, and for appropriately performing processing related to the activation state of the alarm (i.e., management of the alarm state). [Background technology]

[0002] Conventionally, there is known a technology that sounds an alarm from the vehicle when an abnormality, such as an impact caused by a hit-and-run, is detected while the vehicle is parked. In recent years, a technology has been disclosed that records the surroundings of the vehicle when an abnormality is detected and transmits the recording to the driver's mobile phone (for example, see Patent Document 1 below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-87141 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, after detailed consideration by the inventors, it has been found that there is room for improvement in the conventional technology in terms of managing the state of an alarm issued by a vehicle, including stopping the alarm when an alarm is issued by the vehicle (e.g., when an alarm sound is sounded).

[0005] An object of one aspect of the present disclosure is to provide a technique capable of appropriately managing the state of an alarm issued by a vehicle. [Means for solving the problem]

[0006] a) One aspect of the present disclosure relates to an alarm system (1) configured to issue an alarm in a parked vehicle (3) when a predetermined impact corresponding to an abnormality in the vehicle is detected.

[0007] This alarm system is configured so that, when an impact is detected, the image captured by the vehicle-mounted camera (13) is recorded in a specified recording device (23, 55), and a notification is sent to the vehicle user's terminal (71) that the situation requires the user to check the image recorded in the recording device (S310).

[0008] Furthermore, after the notification, the terminal is configured to be able to perform an operation to stop the alarm based on the time elapsed since the detection of the impact or the time elapsed from a reference timing after the detection of the impact, and a signal output from the terminal instructing the operation of the alarm (e.g., a signal to stop the alarm) (S200).

[0009] With this configuration, the state of the alarm issued by the vehicle (e.g., issuance or stop of the alarm) can be appropriately managed. For example, by detecting an abnormal impact and sounding an alarm, it is possible to quickly notify the surroundings of the occurrence of a hit-and-run or the like. Also, in the event of a hit-and-run, since the video of the surroundings of the vehicle is recorded, evidence of the hit-and-run can be secured. Furthermore, since the operation of stopping the alarm can be performed based on the elapsed time from the detection of the impact or the elapsed time from a reference timing after the detection of the impact, and a signal instructing the operation of the alarm (e.g., a signal to stop the alarm) output from the terminal where the user confirmed the video by the notification, it is possible to appropriately stop the alarm.

[0010] b) Another aspect of the present disclosure relates to a terminal for use in an alarm system (1) that issues an alarm when a predetermined impact corresponding to an abnormality in a parked vehicle (3) is detected, and notifies a terminal (71) of a user of the vehicle of information related to the detection of the impact.

[0011] The terminal includes a display control unit (87) and an operation processing unit (89). The display control unit is configured to display the image recorded by the vehicle-mounted camera (13) on the display unit (75) when a notification is received from a device (51) external to the terminal that the situation requires confirmation of the image after the impact has been detected and recorded by the vehicle-mounted camera (13).

[0012] The operation processing unit is configured to transmit, when a user operation to stop an alarm or extend an alarm is performed via the operation unit (77) of the terminal, a signal corresponding to the content of the user operation to a device outside the terminal.

[0013] With this configuration, it is possible to appropriately manage the state of the alarm issued by the vehicle (e.g., issuance or stop of the alarm). For example, when the terminal receives the notification from a device outside the terminal (e.g., a server), the terminal notifies the user of the notification, so that the user can check the video and instruct the alarm to be stopped or continued depending on the situation.

[0014] c) Another aspect of the present disclosure relates to a server (51) configured to acquire information transmitted from a vehicle (3) and to generate an alarm upon detection of a predetermined impact corresponding to an abnormality of the vehicle (3). This server comprises a record processing unit (63), an information notification unit (65), and an information provision unit (67).

[0015] The recording processing unit is configured to, when an image recorded by the vehicle-mounted camera (13) after the detection of an impact is transmitted from the vehicle, record the transmitted image in the recording device (55).

[0016] The information notification unit is configured to, when receiving a notification from the vehicle that it is time to check the video footage recorded by the vehicle-mounted camera, send said notification to a terminal (71) of the vehicle user.

[0017] The information providing unit is configured to provide the vehicle with information indicating whether to stop or continue the alarm depending on whether a signal to stop the alarm or a signal to extend the alarm is received from the terminal.

[0018] With this configuration, the state of the alarm issued by the vehicle (e.g., issuance or termination of the alarm) can be appropriately managed. For example, the server notifies the terminal that it is a situation in which the video recorded in the recording device needs to be checked. After the terminal has checked the situation, the terminal can provide the vehicle (e.g., the on-board device) via the server with information indicating whether to terminate or continue the alarm. Thus, the vehicle can terminate or continue the alarm.

[0019] d) Another aspect of the present disclosure relates to an in-vehicle device (9) configured to issue an alarm when a predetermined impact corresponding to an abnormality in the vehicle (3) is detected while the vehicle is parked. The vehicle-mounted device includes an information recording unit (30), an external providing unit (31), and an alarm determination unit (33).

[0020] The information recording section is configured to record the video image recorded by the vehicle-mounted camera (13) after the impact is detected in a recording device (23). The external providing unit is configured to provide the video recorded in the recording device to an external device (51), and is also configured to notify the external device that it is time to check the video.

[0021] The warning decision unit is configured to decide the timing to stop the warning based on the time elapsed from the detection of the impact or the time elapsed from a reference timing from the detection of the impact, and information indicating whether to stop or continue the warning provided by an external device.

[0022] With this configuration, the state of the alarm issued by the vehicle (e.g., issuance or termination of the alarm) can be appropriately managed. The vehicle-mounted device can appropriately determine the timing to terminate the alarm based on the elapsed time and information indicating whether to terminate or continue the alarm, which are provided from an external device (e.g., a server).

[0023] Furthermore, the symbols in parentheses in this column and in the claims indicate a correspondence with the specific means described in the embodiment described later as one aspect, and do not limit the technical scope of the present disclosure. [Brief description of the drawings]

[0025] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. First embodiment] In the first embodiment, a technology will be described that can issue an alarm in a vehicle and appropriately manage the alarm state when the vehicle is subjected to an abnormal impact due to a hit-and-run or the like.

[0026] [1-1. Overall composition] As shown in FIG. 1, the warning system 1 of the first embodiment mainly includes a device mounted on a vehicle 3, a device used in a cloud 5, and a device used by a user.

[0027] The devices mounted on the vehicle 3 and the devices used in the cloud 5, and the devices used in the cloud 5 and the devices used by the user are each communicatively connected via a communication network such as the Internet.

[0028] Each component of the alarm system 1 will now be described. [1-1-1. Vehicle side equipment] The vehicle 3 includes an on-board device 9, a vehicle ECU 11, an on-board camera 13, a sensor unit 15, an alarm unit 17, etc. Note that ECU is an abbreviation for Electronic Control Unit (that is, electronic control device).

[0029] <In-vehicle device> The on-vehicle device 9 is an electronic processing device that can be mounted on the vehicle 3, for example, by retrofitting, and is connected to the vehicle ECU 11 so as to be able to transmit and receive data thereto.

[0030] The vehicle-mounted device 9 includes an in-vehicle device processing unit 21 that performs various calculation processes related to the operation of the vehicle-mounted device 9, an in-vehicle device recording unit 23 that records (i.e., stores) various data such as video data, an in-vehicle device communication unit 25 that communicates with the server 51, etc. The in-vehicle device recording unit 23 is, for example, a storage such as a hard disk on which data can be rewritten.

[0031] The vehicle-mounted device processing unit 21 is mainly configured with a microcomputer (hereinafter, a microcomputer) having a CPU 27 and semiconductor memories such as ROM and RAM (hereinafter, a memory 29). For example, an alarm status described later is recorded in the memory 29.

[0032] Various functions of the vehicle-mounted device processing unit 21 are realized by the CPU 27 executing a program (for example, a control application described later) stored in a non-transient substantial recording medium. In this example, the memory 29 corresponds to the non-transient substantial recording medium storing the program. Furthermore, by executing this program, a method corresponding to the program is executed.

[0033] The number of microcomputers constituting the vehicle-mounted device processing unit 21 may be one or more. The method of realizing the various functions of the vehicle-mounted device processing unit 21 is not limited to software, and some or all of the elements may be realized using one or more pieces of hardware. For example, when the functions are realized by electronic circuits that are hardware, the electronic circuits may be realized by digital circuits including a large number of logic circuits, or analog circuits, or a combination of these.

[0034] Here, the process carried out by the vehicle-mounted device processor 21 will be described. 2, the in-vehicle device processing unit 21 is configured to issue an alarm when it detects a predetermined impact corresponding to an abnormality in the vehicle 3 (i.e., an abnormal impact caused by a hit-and-run accident or the like) while parked, and functionally includes an information recording unit 30, an external providing unit 31, and an alarm determination unit 33. Note that, hereinafter, an abnormal impact caused by a hit-and-run accident or the like may be simply referred to as an impact.

[0035] The information recording unit 30 is configured to record the video image recorded by the vehicle-mounted camera 13 after the impact is detected in the vehicle-mounted device recording unit 23. The external providing unit 31 is configured to provide the video recorded in the vehicle-mounted device recording unit 23 to the server 51 and to notify the server 51 of the situation in which the video should be checked.

[0036] The warning decision unit 33 is configured to decide the timing to stop the warning based on the time elapsed since the detection of the impact or the time elapsed from a reference timing since the detection of the impact, and information provided by the server 51 indicating whether to stop or continue the warning.

[0037] <Vehicle ECU> Returning to Fig. 1, the vehicle ECU 11 is an electronic control device that controls the operation of the vehicle 3, and is communicably connected to the in-vehicle device 9. The vehicle ECU 11 includes a vehicle control unit 35 that performs various calculation processes related to the control of the operation of the vehicle 3. Although not shown, the vehicle control unit 35 is generally configured with a microcomputer having a CPU and memories such as a ROM, a RAM, and a flash memory.

[0038] The configuration for implementing the various functions of the vehicle control unit 35 and the configuration of hardware, etc. are similar to those of the in-vehicle device processing unit 21 described above. Here, the hardware configuration in the vehicle 3 connected to the vehicle ECU 11 will be described.

[0039] 3, in the vehicle 3, the vehicle ECU 11 connected to the in-vehicle device 9 is connected to a plurality of ECUs 43 and the like via an in-vehicle communication network 41 that performs communication within the vehicle. In addition, each ECU 43 is connected to each of the other ECUs 45 so as to be able to communicate with each other.

[0040] The vehicle ECU 11 can realize coordinated control of the entire vehicle 3 by controlling the multiple ECUs 43. Each ECU 43 is provided for each domain divided by the function in the vehicle 3, and can mainly control the multiple ECUs 45 present in that domain. The domains are, for example, a power train, a body, a chassis, a cockpit, etc. The ECUs 45 are, for example, ECUs that control sensors and actuators. The in-vehicle device 9 is electrically connected to a battery of the vehicle 3, and shares a power source with the vehicle ECU 11, the ECU 43, and the ECU 45.

[0041] <In-vehicle camera> 1, the vehicle-mounted camera 13 may be a CCD camera or the like. The vehicle-mounted camera 13 may be a camera that photographs the surroundings of the vehicle 3 or a camera that photographs the interior of the vehicle 3.

[0042] The vehicle-mounted camera 13 may start recording when it detects an impact caused by a hit-and-run by another vehicle, or may record continuously. As described later, when transmitting captured video from the vehicle-mounted device 9 to the server 51, at least the video after the impact is detected is transmitted. Specifically, when shooting is started after the impact is detected, the video captured after the impact is detected is transmitted. When shooting continuously, the video captured after the impact is detected is transmitted, but the video immediately before the impact may also be transmitted.

[0043] Although not shown, ambient sound may be recorded by a microphone in addition to shooting the video. Since sound information is recorded together with the video information, the sound information can also be transmitted when the video is transmitted.

[0044] <Sensor section> The sensor unit 15 is a device that detects the state of the vehicle 3, etc. An example of this sensor unit 15 is a known impact sensor 15a that detects an impact when the vehicle 3 receives an impact due to a hit-and-run caused by another vehicle, etc.

[0045] The impact sensor 15a may be, for example, an acceleration sensor that uses piezoelectric ceramics to detect acceleration caused by an impact. In other words, when an impact (i.e., acceleration) of a certain strength or more is detected, it can be considered that an impact due to a hit-and-run accident or the like has occurred.

[0046] Another example is the seating sensor 15b, which is a pressure sensor that detects when a person is seated on the seat. <Alarm part> The alarm unit 17 is a device that, when it detects an abnormal impact due to a hit-and-run accident or the like on the vehicle 3, notifies the surroundings of the vehicle 3 of the occurrence of the abnormality. Examples of the alarm unit 17 include a horn 17a and a light 17b. Note that examples of the light 17b include a hazard lamp.

[0047] [1-1-2. Cloud side device] As shown in FIG. 1, the cloud 5 includes a server 51 as a device for performing various operations in the cloud 5.

[0048] The server 51 includes a server processing unit 53 that performs various calculation processes related to the operation of the server 51, a server recording unit 55 that records various data such as a video database (i.e., a video DB), and a server communication unit 57 that communicates with the in-vehicle device 9 and the user's terminal 71. The server recording unit 55 is, for example, a storage device such as a hard disk on which data can be rewritten.

[0049] The server processing unit 53 is mainly configured with a microcomputer having a CPU 59 and a memory 61 such as a ROM, a RAM, etc. For example, the alarm status is recorded in the memory 61.

[0050] The various functions of the server processing unit 53 are similar to those of the in-vehicle device processing unit 21. In other words, the various functions of the server processing unit 53 are realized by the CPU 59 executing a program stored in a non-transient real recording medium. The number of microcomputers constituting the server processing unit 53 may be one or more.

[0051] Furthermore, the method of realizing the various functions of the server processing unit 53 is not limited to software, and some or all of the elements may be realized using one or more pieces of hardware. For example, when the above functions are realized by electronic circuits that are hardware, the electronic circuits may be realized by digital circuits including a large number of logic circuits, or analog circuits, or a combination of these.

[0052] Here, the processing contents executed by the server processing unit 53 will be described. As shown in FIG. 4, the server processing unit 53 is configured to acquire information transmitted from the vehicle 3 and issue an alarm when a predetermined impact corresponding to an abnormality in the vehicle 3 is detected, and functionally includes a recording processing unit 63, an information notification unit 65, and an information provision unit 67.

[0053] The recording processing unit 63 is configured to record the transmitted video in the server recording unit 55 when video recorded by the vehicle-mounted camera 13 after the impact is detected is transmitted from the vehicle 3.

[0054] The information notification unit 65 is configured to, when receiving a notification from the in-vehicle device 9 that it is now time to check the video recorded by the in-vehicle camera 13, send the notification to the terminal 71 of the user of the vehicle 3. The notification may be a notification that enables checking of the video recorded in the server recording unit 55, in other words, warning information indicating that an abnormal impact has been detected (for example, information that the warning status is on).

[0055] The information providing unit 67 is configured to provide the vehicle 3 (i.e., the in-vehicle unit 9) with information indicating whether to stop or continue the alarm depending on whether a signal to stop the alarm or a signal to extend the alarm is received from the terminal 71.

[0056] [1-1-3. User side equipment] Returning to Fig. 1, an example of a device used by a user is an information terminal (hereinafter, terminal) 71. Examples of the terminal 71 include well-known smart phones (i.e., smartphones), tablet terminals, and personal computers such as notebook computers.

[0057] The terminal 71 includes a terminal processing unit 73 that performs various calculation processes related to the operation of the terminal 71, a display 75, a speaker 76, an operation unit 77 that allows various inputs to be made manually, and a terminal communication unit 79 that allows communication with the server 51, etc. If the display 75 has a touch panel function, the operation unit 77 may also be a touch panel.

[0058] The terminal processing unit 73 is mainly configured with a microcomputer having a CPU 81 and a memory 83 such as a ROM and a RAM. The various functions of the device processing unit 73 are similar to those of the in-vehicle device processing unit 21. That is, the various functions of the device processing unit 73 are realized by the CPU 81 executing a program (for example, a terminal application) stored in a non-transient substantial recording medium. The number of microcomputers constituting the device processing unit 73 may be one or more.

[0059] Furthermore, the method of realizing the various functions of the device processing unit 73 is not limited to software, and some or all of the elements may be realized using one or more pieces of hardware. For example, when the above functions are realized by electronic circuits that are hardware, the electronic circuits may be realized by digital circuits including a large number of logic circuits, or analog circuits, or a combination of these.

[0060] Here, the processing contents executed by the terminal processing unit 73 will be described. 5, the terminal processing unit 73 performs various processes in the terminal 71 used in the alarm system 1. The alarm system 1 is a system that issues an alarm when it detects a predetermined impact corresponding to an abnormality in a parked vehicle 3, and notifies the terminal 71 of the user of the vehicle 3 of information related to the detection of the impact.

[0061] The device processing unit 73 functionally comprises a display control unit 87 and an operation processing unit 89. When the display control unit 87 is notified by the server 51 that it is time to review the video footage recorded by the vehicle-mounted camera 13 after the impact has been detected, the display control unit 87 is configured to display the video footage recorded by the vehicle-mounted camera 13 (i.e., the video footage uploaded to and recorded on the server 51) on the display 75.

[0062] The operation processing unit 89 is configured such that when a user operation to stop an alarm or extend an alarm is performed by the operation unit 77, the operation processing unit 89 transmits a signal corresponding to the content of the user operation to the server 51 via the terminal communication unit 79.

[0063] [1-2. Operation in the alarm system] Next, the operation of the entire alarm system 1 will be described. The alarm system 1 is a system configured to issue an alarm in a parked vehicle 3 when a predetermined impact corresponding to an abnormality in the vehicle 3 is detected.

[0064] As will be described in detail later, when the vehicle 3 detects an impact, the alarm system 1 is configured to record the image captured by the vehicle-mounted camera 13 in the vehicle-mounted device recording unit 23, which is a recording device, and the server recording unit 55. At the same time, the alarm system 1 is configured to notify the terminal 71 of the user of the vehicle 3 that it is now time to check the image recorded in the server recording unit 55 (i.e., the alarm status is on).

[0065] Furthermore, after the notification, the device is configured to be able to perform an operation to stop the alarm based on the time that has elapsed since the detection of the impact or the time that has elapsed since a reference timing after the detection of the impact, and a signal that instructs the alarm operation output from terminal 71.

[0066] The operation of each component of the alarm system 1 will now be specifically described. [1-2-1. Operation in vehicle] 6, when the impact sensor 15a of the sensor unit 15 detects an impact due to a hit-and-run or the like, a signal from the impact sensor 15a (i.e., an impact detection signal) is transmitted to the vehicle-mounted device 9. This impact detection signal serves as a start-up trigger for starting the operation of the vehicle-mounted device 9.

[0067] This activation trigger activates a control application (i.e., software for performing predetermined control in the in-vehicle device 9) of the in-vehicle device 9. A control signal by the control application is transmitted to the in-vehicle camera 13 and other devices of the vehicle 3 via EdgeAPI (i.e., API on the in-vehicle device side). Note that API is an abbreviation for Application Programming Interface.

[0068] Specifically, the horn 17a and the lights 17b of the vehicle 3 are activated by the control application, and the in-vehicle camera 13 starts capturing images. Furthermore, the images (for example, videos) captured and recorded by the in-vehicle camera 13 are recorded in the in-vehicle device recording unit 23 by the control application (that is, the video data is managed).

[0069] Furthermore, the control application issues an instruction to change the warning status recorded in the memory 29 via the EdgeAPI. This warning status is an index indicating whether or not a warning should be issued (i.e., an index regarding an abnormality due to an impact on the vehicle 3). The warning status is set to OFF when no impact due to a hit-and-run or the like (i.e., an abnormal impact) is detected, and is set to ON when an abnormal impact is detected.

[0070] Furthermore, the control application instructs uploading of the video recorded in the in-vehicle device recording unit 23 to the server 51 via the EdgeAPI. The warning status is transmitted to the server 51 by the in-vehicle communication unit 25. In addition, the video recorded in the in-vehicle recording unit 23 is transmitted to the server 51 by the in-vehicle communication unit 25.

[0071] [1-2-2. Operation on the server] The warning status transmitted from the vehicle-mounted device 9 is transmitted to the memory 61 of the server 51 via the server communication unit 57 and CloudAPI (i.e., API on the cloud side), and is updated and recorded in the memory 61. This allows the warning status recorded in the memory 29 of the vehicle-mounted device 9 and the warning status recorded in the memory 61 of the server 51 to be synchronized.

[0072] Among the alarm statuses of the server 51, an alarm status indicating that an abnormal impact has occurred (i.e., information indicating that the alarm status is ON) is transmitted to the terminal 71 via the server communication unit 57 by software (i.e., server software) that controls the operation of the server 51. The server 51 has a function as a back-end server for the terminal application.

[0073] On the other hand, as described below, when the server 51 receives an instruction from the terminal 71 to change the alarm status, the server 51 changes the alarm status in the memory 61 of the server 51. Furthermore, when the alarm status of the server 51 is changed in this way, the information is transmitted to the vehicle-mounted device 9, and the alarm status in the memory 29 of the vehicle-mounted device 9 is also changed in the same way. This causes the alarm status of the server 51 and the vehicle-mounted device 9 to be synchronized.

[0074] Moreover, the video transmitted from the vehicle-mounted device 9 to the server 51 is recorded in the server recording unit 55 via the server communication unit 57. The video recorded in the server recording unit 55 is configured to be viewable (that is, viewable) by the terminal 71 through video hosting.

[0075] [1-2-3. Operation on the terminal] When the server 51 transmits an alarm status indicating that an abnormal impact has occurred to the terminal 71, i.e., when a notification that the alarm status is ON is given, the content corresponding to the alarm status being ON is notified to the user via the display 75 and speaker 76 of the terminal 71. For example, the occurrence of an abnormal impact and the ON state of the alarm status are notified to the user by images, sounds, etc.

[0076] Furthermore, when a notification is given that the alarm status is on, the video recorded in the server recording unit 55 can be viewed from the terminal 71 by so-called video hosting.

[0077] That is, by accessing the server 51 from the terminal 71, the user can view the video recorded in the server recording unit 55 (i.e., the video after the impact is detected, captured by the vehicle-mounted camera 13) using the display 75 of the terminal 71. If the video also contains sound information such as voice, the user can also hear the sound at the same time.

[0078] When terminal 71 is notified that the alarm status is on, the video may be automatically accessed from terminal 71 so that it can be viewed on display 75 of terminal 71. Alternatively, the user may be allowed to select whether or not to view the video on terminal 71, and the video may be displayed when the user selects to view the video by operating operation unit 77.

[0079] Then, if the user watches the video and determines that no abnormality is detected, for example, if the user determines that the impact sensor 15a or the like is malfunctioning due to the influence of wind or the like, the user can operate the operation unit 77 to instruct the server 51 to change the alarm status to a state where there is no abnormality (i.e., the alarm status is turned off).

[0080] When a signal to change such an alarm status to OFF is transmitted from the terminal 71, the server 51 changes the alarm status to OFF in the memory 61. At the same time, a signal to change the alarm status to OFF is transmitted from the server 51 to the vehicle-mounted device 9, so that the vehicle-mounted device 9 changes the alarm status in the memory 29 to OFF.

[0081] This stops the alarm operation (i.e., the operation of alerting the surroundings of an abnormality using the horn 17a and the light 17b) being performed by the in-vehicle device 9. The alarm operation is configured to stop after a preset period of time has elapsed even if there is no instruction to start the alarm operation. When the alarm operation is stopped, video recording and uploading are also stopped.

[0082] On the other hand, if the user judges that some abnormality has occurred after watching the video, the user can operate the operation unit 77 to extend the period of the warning action. In other words, the alarm operation is configured to stop when a preset certain time (i.e., a predetermined alarm period: default period) has elapsed, but the alarm operation can be extended for a certain time (i.e., an alarm extension period) so that the alarm operation does not end even after the alarm period has elapsed.

[0083] Specifically, when an instruction to extend the warning period is given from the terminal 71, a control signal is transmitted to the server 51, and further transmitted from the server 51 to the vehicle-mounted device 9, so that the vehicle-mounted device 9 can extend the warning operation. Note that while the warning operation is being performed, the warning status is ON. Note that while the warning operation is being performed, video recording and video uploading are also performed.

[0084] The warning period may be a predetermined period (e.g., a period set in advance) from when the shock sensor 15a detects an abnormal shock and starts issuing a warning. Alternatively, the warning period may be a predetermined period from when the shock sensor 15a detects an abnormal shock and starts issuing a warning at a reference timing. The reference timing may be a time (period) set in advance.

[0085] [1-3. Control processing] Next, the processing performed in the first embodiment will be described. [1-3-1. Processing in the vehicle] First, the process performed by the vehicle-mounted device processing unit 21 of the vehicle-mounted device 9 and the like will be described with reference to the flowchart of FIG.

[0086] This process is performed at regular intervals while the vehicle is parked. Here, "while parked" refers to a state in which the well-known ignition switch and start switch (i.e., push start button), which are switches for driving the vehicle 3, are off. Even in this state, power is supplied to the in-vehicle device 9, so that the control application and the like can operate.

[0087] 7, in step (hereinafter, S) 100, it is determined whether or not an impact has been detected. Specifically, it is determined whether or not an abnormal impact caused by a hit-and-run or the like has been detected based on a signal from the impact sensor 15a. If the determination here is affirmative, the process proceeds to S110, whereas if the determination here is negative, the process is temporarily terminated.

[0088] In S110, since an abnormal impact due to a hit-and-run or the like has been detected, the warning status is set to ON. In the next step S120, the control application startup timer is reset and timing is started. That is, a predetermined time is set as the time for issuing an alarm (that is, a preset initial alarm time).

[0089] In the next S130, the horn 17a and the light 17b are activated to sound an alarm to notify the surroundings of the vehicle 3 of an abnormality. Also, the in-vehicle camera 13 is activated to start recording an image of the surroundings of the vehicle 3. Furthermore, the recorded image (i.e., a video) is uploaded to the server 51.

[0090] In the next S140, similar to S100, it is determined whether an abnormal impact has been detected. That is, it is determined whether an abnormal impact has been detected again. If the determination here is affirmative, the process returns to S120, whereas if the determination here is negative, the process proceeds to S150. Therefore, if an impact is detected again, the timer is reset and the predetermined time is set again.

[0091] While the timer is running, the alarm status is constantly monitored, and as described below, when the alarm status is switched to off, the alarm, recording, and video uploading are stopped, and the vehicle-mounted unit 9 goes into sleep mode.

[0092] In S150, it is determined whether the alarm status is ON. If the determination is affirmative, the process proceeds to S160, whereas if the determination is negative, the process proceeds to S200. As described below, when the alarm status of the server 51 is turned off by operating the terminal 71, the server 51 notifies the vehicle-mounted unit 9 that the alarm status is off. Therefore, when the vehicle-mounted unit 9 receives a notification that the alarm status is off from the server 51, the alarm status of the vehicle-mounted unit 9 also turns off, and the operations of alarming, recording, and uploading the recording are terminated.

[0093] In S160, since the alarm status is ON, the alarm, recording, and uploading of the recording are continued. In the next step S170, the timer ends timing after a predetermined time has elapsed since the start of timing by the startup timer.

[0094] In the next S180, it is determined whether the extension flag is on. This extension flag is a flag that is set when an instruction to extend the warning period is given via the server 51 by operating the terminal 71. If the determination is affirmative, the process returns to S120, whereas if the determination is negative, the process proceeds to S190. In other words, if the extension flag is on, the timer is reset and the predetermined time is set again.

[0095] Incidentally, if the extension flag is turned on by an operation on the terminal 71 before the predetermined time, as will be described later, the process returns to S120 and the timer is set again. In S190, the warning status is set to OFF. That is, since a preset time (i.e., warning period) has elapsed since the detection of the abnormal impact, and the extension flag is OFF, the warning status is set to OFF.

[0096] In the next step S200, since the warning status is OFF, the warning is stopped, recording is stopped, and uploading of the recording to the server 51 is stopped. In the next step S210, the vehicle-mounted device 9 is put into a sleep state, and the process ends.

[0097] The sleep state is a state in which the functions of the vehicle-mounted device 9 are stopped or reduced until a signal for activating the vehicle-mounted device 9 (for example, a wake-up signal notifying the detection of an abnormal impact) is input.

[0098] If a status that can be operated by the EdgeAPI is prepared separately, it is possible to individually control any of the alarm, recording, and video upload from the terminal 71. [1-3-2. Processing on the server] Next, the process executed by the server processing unit 53 of the server 51 and the like will be described with reference to the flowchart of FIG.

[0099] This process is performed at regular intervals. 8, in S300, it is determined whether or not the alarm status recorded in the memory 61 of the server 51 is ON. If the determination here is affirmative, the process proceeds to S310, whereas if the determination here is negative, the process is temporarily terminated.

[0100] In S310, the terminal 71 is notified that the alarm status is ON. In the next S320, it is determined whether or not a video has been uploaded from the vehicle-mounted device 9. In other words, it is determined whether or not the video transmitted from the vehicle-mounted device 9 has been recorded in the server recording unit 55. If the determination here is affirmative, the process proceeds to S330, whereas if the determination here is negative, the process proceeds to S340.

[0101] In the next step S330, the video is hosted. That is, by accessing the server 51 from the terminal 71, the video recorded in the server recording unit 55 can be viewed on the display 75 of the terminal 71. This makes it possible to check the video on the terminal 71.

[0102] In the next S340, it is determined whether or not the alarm status in the memory 61 of the server 51 is ON. If the determination here is affirmative, the process proceeds to S320, whereas if the determination here is negative, the process proceeds to S350. In S350, the terminal 71 is notified that the alarm status is OFF, and this process ends for the time being. Note that the alarm status is constantly monitored, and when it becomes OFF, the terminal 71 is notified that the alarm status has become OFF.

[0103] [1-3-3. Processing on the terminal] Next, the process executed by the terminal processing unit 73 of the terminal 71 and the like will be described with reference to the flowchart of FIG.

[0104] This process is performed at regular intervals. 9, in S400, it is determined whether or not a notification that the alarm status is ON has been received from the server 51. If the determination here is affirmative, the process proceeds to S410, whereas if the determination here is negative, the process is temporarily terminated.

[0105] In S410, it is determined whether or not an operation to turn off the warning status has been performed by the user's operation of the terminal 71. If the determination is affirmative, the process proceeds to S440, whereas if the determination is negative, the process proceeds to S420. Note that the operation to turn on the extension flag can also be performed at any time by the operation of the terminal 71.

[0106] In S420, the terminal 71 (more specifically, the terminal processing unit 73) judges whether or not the video has been uploaded to the server 51. In other words, it judges whether or not the video recorded in the server recording unit 55 of the server 51 is in a state where it can be viewed on the terminal 71 by the above-mentioned video hosting. If the judgment here is affirmative, the process proceeds to S430, whereas if the judgment here is negative, the process returns to the above-mentioned S410.

[0107] In S430, the terminal 71 (more specifically, the terminal processing unit 73) displays the video uploaded to the server 51 on the display 75 of the terminal 71. In the next S440, it is determined whether or not a notification of the alarm status being OFF has been received from the server 51. If the determination here is affirmative, the present process is temporarily terminated, whereas if the determination here is negative, the process returns to S410.

[0108] After the video is displayed, when a notification of turning off the warning status by a user operation or a notification of turning off the warning status by the expiration of the timer of the vehicle-mounted device 9 is received, this process ends. [1-4. Effects] According to the first embodiment, the following effects can be obtained.

[0109] (1a) The alarm system 1 of the first embodiment is configured to, when an impact is detected, record the image captured by the in-vehicle camera 13 in the in-vehicle device recording unit 23 and notify the terminal 71 of the user of the vehicle 3 of the alarm status. Furthermore, after the notification, the alarm is stopped based on the time elapsed since the detection of the impact or the time elapsed since a reference timing after the detection of the impact and a signal output from the terminal 71 instructing the alarm operation (for example, a signal to stop the alarm).

[0110] With this configuration, the state of the alarm issued by the vehicle 3 (for example, issuance or stopping of the alarm) can be appropriately managed. For example, by detecting an abnormal impact and sounding an alarm, it is possible to promptly notify the surroundings of the occurrence of a hit-and-run or the like. Furthermore, in the event of a hit-and-run, since the video of the area around the vehicle 3 is recorded, evidence of the hit-and-run can be secured. Furthermore, even if the alarm sounds due to a false detection, the user can check the video through the notification, so it is possible to appropriately stop the alarm.

[0111] (1b) In the first embodiment, if a signal to stop the alarm is not transmitted from the terminal 71 to the server 51, the alarm can be stopped when the elapsed time reaches a predetermined time (for example, the expiration of a preset alarm period). This makes it possible to stop the alarm at an appropriate timing.

[0112] (1c) In the first embodiment, if a signal to stop the alarm is transmitted from the terminal 71 to the server 51 before the elapsed time reaches the predetermined time, the alarm can be stopped. This makes it possible to prevent an alarm from being issued more than necessary and to stop the alarm at an appropriate timing.

[0113] (1d) In the first embodiment, when a signal to stop the alarm is not transmitted from the terminal 71 to the server 51, if an impact is detected again during the alarm after the detection of the impact that started the alarm, the alarm can be stopped at a later timing than when no impact is detected again. This makes it possible to issue an alarm for a required period of time.

[0114] (1e) In the first embodiment, if a signal to continue the alarm is transmitted from terminal 71 to server 51 before the elapsed time reaches the predetermined time, the alarm can be stopped at a later timing than when there is no signal to continue the alarm. This makes it possible to stop the alarm at an appropriate timing.

[0115] (1f) In the first embodiment, the vehicle-mounted device 9 can start up in response to the detection of an impact and can go to sleep in response to the termination of the alarm. This allows the vehicle-mounted device 9 to operate for a required period of time and reduce power consumption. Since the power consumption of the vehicle-mounted device 9, which is powered by the battery of the vehicle 3, can be reduced, power consumption of the battery of the vehicle 3 can be suppressed.

[0116] (1g) In the first embodiment, when the terminal 71 receives a notification from the server 51 that the alarm status is on, it can notify the user of this by driving the display 75 and the speaker 76. Also, the video recorded by the in-vehicle camera 13 (i.e., the video recorded in the server 51) can be displayed on the display 75. Furthermore, the operation unit 77 can be used to perform a user operation to stop the alarm and a user operation to extend the alarm.

[0117] (1h) In the first embodiment, when the server 51 receives from the vehicle 3 an image recorded by the vehicle-mounted camera 13 after the detection of the impact, the server 51 can record the transmitted image in the server recording unit 55. Furthermore, when the server 51 receives alarm status information from the vehicle-mounted device 9, the server 51 can notify the terminal 71 of the user of the vehicle 3 of the alarm status. Furthermore, the server 51 can provide the vehicle 3 (i.e., the vehicle-mounted device 9) with information indicating whether to stop or continue the alarm depending on whether a signal to stop the alarm or a signal to extend the alarm has been received from the terminal 71.

[0118] (1i) In the first embodiment, the vehicle-mounted device 9 can provide the server 51 with video after the detection of an impact, which video is recorded by the vehicle-mounted camera 13. Also, the vehicle-mounted device 9 can determine the timing to stop the warning based on the time elapsed since the detection of the impact or the time elapsed since a reference timing after the detection of the impact, and information provided by the server 51 indicating whether to stop or continue the warning.

[0119] [1-5. Correspondence] Next, the relationship between the first embodiment and the present disclosure will be described. The alarm system 1 corresponds to an alarm system, the vehicle 3 corresponds to a vehicle, the in-vehicle unit 9 corresponds to an in-vehicle unit, the in-vehicle camera 13 corresponds to an in-vehicle camera, the in-vehicle unit recording unit 23 and the server recording unit 55 correspond to a recording device, the server 51 corresponds to a server, and the terminal 71 corresponds to a terminal.

[0120] [2. Second embodiment] Since the second embodiment has a basic configuration similar to that of the first embodiment, the following mainly describes the differences from the first embodiment. Note that the same reference numerals as those in the first embodiment indicate the same configuration, and the preceding description is to be referred to.

[0121] In the second embodiment, a process in the case where there are a plurality of control applications will be described. [2-1. Configuration] The alarm system 1 of the second embodiment has a configuration similar to that of the first embodiment, as shown in Fig. 10. Specifically, like the first embodiment, the alarm system 1 includes an in-vehicle device 9, a server 51, and a terminal 71.

[0122] The configurations and operations of the vehicle-mounted device 9, the server 51, and the terminal 71 are basically the same as those in the first embodiment, so a description thereof will be omitted. The following description will focus on the differences. In the second embodiment, in addition to the control application similar to that in the first embodiment, other applications are provided. For example, an application A detects that a person is sitting in a seat based on information from the seating sensor 15b, and an application B detects that a baby is in the vehicle based on the result of recognizing an image taken by the vehicle-mounted camera 13 (however, the vehicle-mounted camera 13 takes an image of the interior of the vehicle).

[0123] Therefore, in the second embodiment, the control application and the other two types of applications (that is, application A and application B) can control any other two types of status via the EdgeAPI. The optional other statuses include an A status (i.e., a seated flag) that indicates information on whether a person is seated. The A status is on when a person is seated, and is off when a person is not seated.

[0124] In addition, the optional other status includes a B status (i.e., a baby flag) that indicates information about a baby in the car, which is turned on when there is a baby in the car and turned off when there is no baby in the car.

[0125] The two arbitrary statuses are recorded in the memory 29 of the vehicle-mounted device 9, for example. Therefore, it is possible to change the warning status based on the other two statuses operated by the other two apps, as described below. Note that the other statuses may be one type or three or more types.

[0126] [2-2. Operation] Next, the operation of the alarm system 1 of the second embodiment will be described with reference to the flow chart of FIG.

[0127] The flowchart in FIG. 11 shows the processes executed by the vehicle-mounted device processing unit 21 of the vehicle-mounted device 9 and the like, and among these, the processes shown within the dashed line frame are processes specific to the second embodiment.

[0128] Incidentally, the processes on the server 51 side and the terminal 71 side are basically the same as those in the first embodiment, and therefore the description thereof will be omitted. 11, in S500, it is determined whether or not an abnormal impact that occurs during a hit-and-run accident or the like has been detected based on a signal from the impact sensor 15a. If the determination here is affirmative, the process proceeds to S510, whereas if the determination here is negative, the process is temporarily terminated.

[0129] In S510, since an abnormal impact due to a hit-and-run or the like has been detected, the warning status is set to ON. In the next S520, it is determined whether or not a seat pressure indicating that a person is in the seat is detected based on the signal from the seat sensor 15b. In other words, it is determined whether or not a seating flag (i.e., A status) indicating that a person is in the seat is on. If the answer is YES, the process proceeds to S530, whereas if the answer is NO, the process proceeds to S540.

[0130] In S530, it is determined whether or not the baby flag (i.e., B status) is on. If the determination here is affirmative, the process proceeds to S540, whereas if the determination here is negative, the process proceeds to S640. In S540, the startup time timer of the control application is reset and timing is started.

[0131] In the next S550, the horn 17a and the light 17b are activated to sound an alarm to notify the surroundings of the vehicle 3 of an abnormality. Also, the in-vehicle camera 13 is activated to start recording an image of the surroundings of the vehicle 3. Furthermore, the recorded image (i.e., a video) is uploaded to the server 51.

[0132] That is, if the seat flag is off in S520 (i.e., no one is seated), the timer is immediately set and an alarm or other action is taken. Also, if the seat flag is on in S520 (i.e., someone is seated) and the baby flag is on (i.e., there is a baby), an alarm or other action is taken, but if the baby flag is off, no alarm or other action is taken.

[0133] In the next S560, it is determined whether or not an abnormal impact has been detected, similarly to S500. If the determination here is affirmative, the process returns to S540, whereas if the determination here is negative, the process proceeds to S570. In S570, it is determined whether the alarm status is ON. If the determination is affirmative, the process proceeds to S580, whereas if the determination is negative, the process proceeds to S630.

[0134] In S580, the alarm, recording, and uploading of the recording are continued. In the next S590, the timer ends timing after a predetermined time has elapsed since the start of timing by the startup timer.

[0135] In the next S600, it is determined whether the extension flag is on. If the determination is affirmative, the process returns to S540, whereas if the determination is negative, the process proceeds to S610. In S610, as in S520, it is determined whether or not a seat pressure indicating that a person is in the seat is detected. In other words, it is determined whether or not the seating flag (i.e., A status) is on. If the answer is YES, the process proceeds to S630, whereas if the answer is NO, the process proceeds to S620.

[0136] In S620, as in S530, it is determined whether or not the baby flag (i.e., B status) is on. If the determination here is affirmative, the process returns to S540, whereas if the determination here is negative, the process proceeds to S630.

[0137] In S630, the warning is stopped, the recording is stopped, and the uploading of the recording to the server 51 is stopped. That is, when the seat flag is on in S610 (i.e., when a person is seated), the operation such as warning is stopped. Also, when the seat flag is off in S610 (i.e., when no person is seated) and the baby flag is on in S620 (i.e., when a baby is present), the operation such as warning is continued.

[0138] In the next step S640, the warning status is set to OFF. In the next step S650, the vehicle-mounted device 9 is put into a sleep state, and the process ends. [2-3. Effects] The second embodiment provides the same effects as the first embodiment.

[0139] Furthermore, in the second embodiment, it is possible to determine whether to issue an alarm based on the situation in the vehicle 3 when an abnormal impact is detected, for example, the seating status of people or the presence of a baby inside the vehicle.

[0140] Furthermore, in the second embodiment, if a signal to stop the alarm is not transmitted from the terminal 71 to the server 51, and the situation of the vehicle 3 during the alarm is a specific situation (for example, a situation where a person is seated and a baby is in the vehicle), the alarm can be configured to continue even if the normal elapsed time until the alarm is stopped reaches a predetermined time. This further improves safety.

[0141] 3. Other embodiments Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take various forms.
